digitalmars.D.bugs - Compiler crash related to arrays

DMD v 0.128, Windows XP SP2.
Caused by either modifying the length of a static array of undefined size:
--
void main(char[][] args) {
int[UNDEFINED] foo;
foo.length = 1;
}
--
or by modifying the length of an associative array:
--
void main(char[][] args) {
int[int] foo;
foo.length = 1;
}
--
Both give a couple of expected errors followed by a compiler crash, in
the form of Windows reporting that "dmd.exe has encountered a problem", etc.
BTW, about DStress: is there an error in "bug cod2 4211 U"? Shouldn't
the assert make sure that the result is 6, not 3?
